Hanging frame of the ceiling fan

ABSTRACT

An improved hanging frame of the ceiling fan includes a supporting base having a plurality of holding parts and extending downwards with a plurality of supporting parts. Each of the holding parts has a first supporting section that extends with a first holding section. Each of the supporting part supports the conversion base from the bottom of a through hole, thereby positioning the ceiling fan.

BACKGROUND OF THE INVENTION

1. Field of Invention

The invention relates to an improved hanging frame of the ceiling fanand, in particular, to the hanging frame that supports a ceiling fanconversion base.

2. Related Art

FIGS. 5 and 6 show a hanging frame of the ceiling fan in the prior art.It has a supporting base 9 whose one side has an opening 91. Both sidesof the opening 91 on the supporting base 9 extend upwards with an earpart 92, respectively. The end of each of the ear parts 92 is providedwith a fixing part 93 outwards. The center of the supporting base 9 hasa through hole 94. The rim of the through hole 94 on the supporting base9 extends upwards with several supporting parts 95.

Please refer to FIG. 7 for a second hanging frame of the ceiling fan. Ithas a supporting base 9A whose one side has an opening (not shown). Bothsides of the opening on the supporting base 9A extend upwards with anear part 92A, respectively. The end of each of the ear parts 92A isprovided with a fixing part 93A outwards. The center of the supportingbase 9A has a through hole 94A. The rim of the through hole 94A on thesupporting base 9A extends downwards with several supporting parts 95A.

As seen in the above-mentioned conventional structures, when theconversion base 96 of a ceiling fan is hung on the supporting parts 95in the through hole 94 of the supporting base 9 in the first hangingframe or the supporting parts 95A in the through hole 94A of thesupporting base 9A in the second hanging frame, the only contact partsare the supporting part 95 or 95A. Therefore, whether the supportingparts 95 extend upwards along the rim of the through hole 94, as shownin FIGS. 5 and 6, or downwards along the rim of the through hole 94A, asshown in FIG. 7, the supporting area is small. In this case, thesupporting base 9 or 9A has merely the function of supporting theconversion base 96. However, when the ceiling fan is in operation, thereis a certain torque that causes the ceiling fan to wiggle. Thus, whenusing the conventional supporting base 9 or 9A to support the conversionbase 96, the ceiling fan wiggles as it runs. Moreover, the wiggling getsstronger when the ceiling fan is running at high speeds.

Therefore, it is the goal of the invention to solve the wiggling problemof the above-mentioned conventional hanging frame structure.

SUMMARY OF THE INVENTION

An objective of the invention is to provide an improved hanging frame ofthe ceiling fan. Using the holding parts and the supporting parts of thesupporting base in the invention, the conversion base of the ceiling fancan be concurrently held and supported. The ceiling fan is thus morestable during its operation.

Another objective of the invention is to strengthen the supporting baseto prevent its deformation, thereby reducing the wiggling of the ceilingfan. According to the invention, the supporting base uses the secondbuckling parts of a connecting element to connect with the firstbuckling parts near the end of the opening.

The disclosed hanging frame according to the invention includes asupporting base. The two opposite sides on the outer edge of thesupporting base extend upwards with an ear part, respectively. The topend of each of the ear parts extends horizontally outwards with a fixingpart. The supporting base has a through hole inside. It further has anopening on the side adjacent to the two ear parts and in communicationwith the through hole. A positioning protrusion is formed along the rimof the through hole towards its center for positioning the conversionbase of the ceiling fan. The rim of the through hole on the supportingbase is extended upwards with several holding parts and downwards withseveral supporting parts. Each of the holding parts holds the conversionbase. Each of the holding parts is curved upwards to form a firstsupporting section and has a curvature corresponding to that of theround section at the outer edge of the conversion base for supportingit. Each of the holding parts extends from the top edge of the firstsupporting section a first holding section. The first holding sectionshold a straight section extended upwards from the outer edge of theconversion base. The straight section has a diameter equal to themaximum diameter of the round section. Each of the supporting sectionssupports the conversion base from the bottom of the through hole.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will be apparent from the following detaileddescription, which proceeds with reference to the accompanying drawings,wherein the same references relate to the same elements.

Please refer to FIGS. 1 to 3 for a first embodiment of the invention. Inthis embodiment, the improved hanging frame of a ceiling fan has asupporting base 1. The two opposite sides of the outer edge 11 of thesupporting base 1 extend upwards with an ear part 12, respectively. Thetop of each of the ear parts 12 extends horizontally outwards with afixing part 13. In this embodiment, each of the fixing parts 13 hasseveral positioning holes 131 for positioning.

The supporting 1 has a through hole 14 inside. One side of thesupporting base 1 between the two ear parts 12 has an opening 15 incommunication with the through hole 14. The conversion base 2 of aceiling fan (not shown) can enter via the opening 15 and hanging in thethrough hole 14 of the supporting base 1. A positioning protrusion 16 isformed on the edge of the through hole 14 on the supporting base 1towards its center. It positions the conversion base 2 of the ceilingfan. Therefore, the conversion base 2 does not rotate when the ceilingfan is running.

The rim of the through hole 14 extends upwards with several holdingparts 17 and downwards with several supporting parts 18. Each of theholding parts 17 holds the conversion base 2. Each of the supportingparts 18 supports the conversion base 2 from the bottom of the throughhole 14. In this embodiment, each of the holding parts 17 extends in acurve upwards with a first supporting section 171. Each of the firstsupporting sections 171 has a curvature corresponding to that of a roundsection 21 at the outer edge of the conversion base 2. Each of theholding parts 17 extends from the top of the first supporting section171 upwards with a first holding section 172. The first holding section172 holds a straight section 22 extended upwards from the top of theround section 21 at the outer edge of the conversion base 2. Thestraight section 22 has a diameter equal to the maximum diameter of theround section 21. (One can define an imaginary line 4 to divide theround section 21 on the outer edge of the conversion base 2 and thestraight section 22.)

When the conversion base 2 of a ceiling fan is disposed inside thesupporting base 1, each of the holding parts 17 uses its firstsupporting section 171 to support the round section 21 of the conversionbase 2. The first holding section 172 of each of the holding parts 17can slightly hold the straight section 22 of the conversion base 2. Eachof the supporting parts 18 also supports the conversion base 2 at thesame time. As shown in FIG. 3, the first supporting sections 171 and thefirst holding sections 172 of each of the holding part 17 on thesupporting base 1 urge the conversion base 2 by an area larger than theconventional supporting base. Moreover, they concurrently hold andsupport the conversion base 2. When the ceiling fan is operating, theconversion base 2 is more stable than the conventional hanging frame.

Of course, the invention has many other embodiments that differ only indetails. Please refer to FIG. 4 for a second embodiment of theinvention. Both sides of the opening 15 on the supporting base 1 have afirst buckling part 19, respectively, for a connecting element 3 toconnect. In this embodiment, the first buckling part 19 is a protrusionupwards from the end of the supporting base 1 near the opening 15. Bothends of the connecting element 3 respectively have a second bucklingpart 31 that connects with the corresponding first buckling part 19.Each of the second buckling parts 31 is a connecting hole 19 for thecorresponding first buckling part 19 of the supporting base 1. Each ofthe first buckling parts 19 goes through the second buckling part 31 andextends upwards. The protruding part is bent to stop the correspondingsecond buckling part 31, thereby positioning the connecting element 3.

The supporting base 1 has an opening 15 for the conversion base 2 to bedisposed in the through hole 14 when the ceiling fan is connected. Theconversion base supported by the supporting base 1 wiggles when the fanis running. Thus, the opening 15 of supporting base 1 will expand anddeform after the fan is used for some time. The wiggling between theconversion base 2 and the supporting base 1 becomes more apparent. Thesecond buckling parts 31 of the connecting element 3 in this embodimentconnect with the corresponding first buckling parts 19 near the ends ofthe opening 15. This enhances the strength of the supporting base 1 forsupporting the conversion base 2. It prevents the deformation of thesupporting base 1 and strong wiggling of the conversion base 2 as thefan runs.

Although the invention has been described with reference to specificembodiments, this description is not meant to be construed in a limitingsense. Various modifications of the disclosed embodiments, as well asalternative embodiments, will be apparent to people skilled in the art.Therefore, it is contemplated that the appended claims will cover allmodifications that fall within the true scope of the invention.
